How does this actualy works on OPM?

Is the sysLocation used anywhere in OPM?

How do I get "System Location" field filled in my OPM?

Is it SNMP or Custom variable that I need to put in Manualy?

Is there a possibility to create a custom monitor for sysLocation  which can then be used in Advanced reports?

There should be sysLocation avaliable by default in Advanced report by my believes.
